Sharpe, Joliet, Ill.,assignor to Brul Incinerators, Blue Island, 115., a corporation ofIllinois Filed Feb. 21, 1964, Ser. No. 346,457 7 Claims. (Ci. 1l0-8)This invention relates to an improved incinerator construction, and,more particularly, to a novel multi-section incinerator constructionfacilitating portability and onsite assembly.

Commercial incinerators, being both relatively large in size andconstructed of heavy materials, such as steel and firebrick, areexceptionally diflicult to transport from the place of manufacture tothat of eventual use. This problem is further complicated by the factthat the refractory linings therein are quite fragile and accordingly,require extreme care in handling.

Complete field fabrication, while eliminating some transportationproblems, is undesirable because it is both time consuming and costly.Moreover, individual manufacture of each unit at its place of intendeduse, introduces additional problems in both quality control andprecision.

The present invention resolves the foregoing problems and disadvantagesby providing an incinerator construction which is manufactured inseparate units or sections that can be individually transported foron-site assembly. A steel shell functions to protect the refractorylinings of the individual sections, particularly during transportation,while a novel guide means prevents damage thereto during assembly byinsuring mating engagement of the respective incinerator sections.

It is therefore an object of the present invention to provide animproved incinerator construction.

Another object of the present invention is to provide an improvedincinerator construction employing a plurality of separate sectionswhich can be individually transported for on-site assembly.

A further object of the present invention is to provide an improvedmulti-section incinerator construction having a novel guide means forinsuring mating engagement of sections and facilitating on-site assemblythereof.

A yet further object of the present invention is to provide an improvedmulti-section incinerator construction wherein one section thereof isprovided with a novel retractably mounted guide means for folding in aretracted position during transportation of the section.

A still further object of the present invention is to provide animproved multi-section incinerator construction having a means formoving the sections thereof into engagement with each other duringassembly.

Other and further objects of the present invention will be obvious tothose skilled in this art from the following detailed description, whenconsidered in conjunction with the accompanying drawings, wherein:

Referring to the drawings, the reference numeral 11 generally designatesa burning chamber section adapted to be joined to a combustion chambersection 12, to form an assembled incinerator 13, as is illustrated inFIGURE 6. The interiors of the burning and combustion chamber sections11 and 12 include respective layers Illa and 12a of an insulationmaterial, such as rock wool, and inner linings 11b and 12b of refractorymaterials capable of withstanding the high temperatures which developduring incinerator operation. The refractory material, such asfirebrick, however, is relatively heavy and fragile and accordingly,requires special care and handling, particularly during transportation.The incinerator construction of the present invention overcomes theseproblems by the above-recited sectional construction and, by means ofother features which are more fully defined below.

In FIGURE 1, the burning chamber section 11 and combustion chambersection 12 are shown suspended from cable-slings I4 and 14a,respectively, ready to be transported from the place of manufacture to alocation for on-site assembly. A sheet metal covering including a topportion or cover 15, a bottom 16, and respective sidewall portions 17,I8, 19 and 20, which can be welded or otherwise suitably secured to asteel frame (not shown), provides protection for the interior componentsof the burnmg chamber section 11, both while it is being transported tothe assembly site, and later during operation of the assembled unit. Thecombustion chamber section 12 is similarly provided with a sheet metalcovering including a cover 21, a bottom 22, and respective sidewallportions 23, 24, 25 and 26.

In the illustration given, the burning chamber section II is supportedon a pair of rigidly mounted I beams 27, each having a flange 27a whichis welded to the web of a channel beam 28, as is shown in FIGURE 6. Thecombustion chamber section 12, as is illustrated in FIGURE 7, issimilarly supported on a pair of rigidly mounted I beams 29 although,unlike I beams 27, no corresponding channel beams are welded thereto.

Portability of the burning chamber section II is facilitated by theprovision of four hoisting bars 30, positioned at each corner of thesection 11 for convenient attachment with the cable sling 14. Aperturesare formed in a pair of angle bars 31 and in the I beams 27 for slidablyreceiving the hoisting bars 30 which can be extended outwardly of theangle bars 31 during transportation of the section, and can be pushedback in an out of the way position when the section is permanentlylocated. If desired, a limiting member 30a can be welded to the shaft ofthe hoisting bar 36 to prevent accidental loss thereof. The combustionchamber section 12 is similarly provided with a series of four hoistingbars 32 which are slidably mounted to angle bars 33 and I beams 29.

The front face 17 of the burning chamber section has a steel frame 34rigidly mounted thereto with a counterweight portion 35 which is adaptedto receive a manually operated guillotine door covering the chargingport 36. If desired, an electrically actuated door mechanism can beinstalled to facilitate the charging operation. An ash removal port 37is positioned directly below the charging port 22. In order to reducethe shipping weight of the incinerator component 11, the charging andash removal doors can be installed in the field.

The side wall portion 18 of the incinerator sect-ion 11 has aretractably mounted guide means 38 parallel thereto. This guide means ishingedly mounted directly to the I beams 27, as is shown at 38a, andincludes a pair of pro-aligned channel members 39 and 40 having webportions 39a and 46b, and flange portions 3% and 20b, respectively.Reinforcement for the channel members is provided by crossmembers ll, 42and 43, which can be suitably secured thereto by welding. Duringtransportation the guide means 38 can be folded into the retractedposition shown in FIGURES 1 and 2.

A flame port 44 is formed in the side wall 18 and serves to connect theinterior of the burning chamber section 11 with the interior of thecombustion chamber section 12.

The front face 23 of the combustion chamber section 12 can be providedwith an ash removal port 45 so that the ash removal doors for bothsections of the incinerator are close to each other. The top portion orcover 21 of the combustion chamber section 12 has a chimney port 46which is adapted to receive a chimney member (not shown) preferablyafter the two sections have been operatively joined in the field. A neckmember 47 composed of a refractory material extends outwardly of theside wall 26 and is adapted to be snugly received by the flame port 42'.

To insure proper operation of the assembled structure, it has been foundto be of the utmost importance that the outwardly extending neck 47project into the flame port 44 and that there be a close fit betweensuch parts. Since the refractory material of which the neck is formed ishighly frangible, and since the sections 11 and 12 are heavy andextremely cumbersome to shift and align, special guide means 38 areprovided to facilitate assembly of the parts.

In accordance with the principles of the present invention, the flangeportions 2% of the rigidly mounted I beams 29 are sized to be snugly butslidably received within the web portions 39a and 46a of the respectivechannel members 39 and i l). The respective I beams 29 are then guidedby engagements of the flange portions 29a with the respective flangeportions 39a and 40b of the channel members 39 and 4d. Thus, movementsof the combustion chamber section 12 will be confined along apredetermined path which insures mating engagements of the twoincinerator sections. It should be noted that the two sections will alsobe vertically aligned since the combined height of the I beams Z9 andchannel beams 39 and 40 of the guide means 38, on which the combustionchamber section 12 rests, equals that of the welded I beam 27 andchannel beam 28 arrangement on which the burning chamber section rests.

Means for moving the two incinerator sections into operative engagementwith each other is provided by a cable and bracket arrangement whichincludes a pair of brackets 48 rigidly mounted to the bottom of theburning chamber section II. Each of the brackets 48 has a hole 48aformed therein which is adapted to receive one end 49a of a cable or rodmember 49 which can be threaded and fitted with a lock nut 49b forrigidly securing the cable 49. A pair of brackets each having a holeSila, are rigidly fixed to the combustion chamber section 12 andpositioned so that they receive the free end of the cable member 49which is threaded and fitted with a nut 51 that engages the bracketfill, as shown in FIG- URES 6 and 7. Thus, tightening of the threadedmember 51 imparts a force on the brackets 50 which both moves andretains the two sections in operative engagement with each other.

In operation, when it is desired to transport the individual incineratorsections from their place of manufacture, the hoisting bars 30 and 32are extended outwardly from the burning and combustion chamber sections11 and 12 respectively. Cable slings 14 and 140 are then attached to thehoisting bars as is illustrated in FIGURE 1, and the separateincinerator units can be :1 loaded onto a truck for transportation tothe assembly site.

Upon arrival at the desired location, the burning chamber section II. islowered by the cable sling 14 and set in place, the cables are removed,and the hoisting bars 30 are pushed back in place. The channel guidemeans 38 is then swung from its retracted position to a horizontalposition. Cable members 49 are secured to the brackets 48. The hoistingbars on the combustion chamber sectlon are then pulled out and attachedto the cable sling Ma and this section is lowered so that its side wall26 is adjacent the side wall 18 of the burning chamber section ll.Before the combustion chamber section 12 is lowered closely in place tothe burning chamber section 11 the mating surfaces of the neck member 47and flame port 44 should be coated with a sufilcient quantity of hightemperature cement to assure sealing engagement. The combustion chambersection 12 is then carefully oriented so that its rail or skid members29 are received by the web portions of the respective channel members 39and 40. Thus, the rail members 29 will be guided by the channel guidemember 38 to insure mating engagement of the respective incineratorsections. After the sections are pushed as close together as possible,the cable sling 14a can be removed and the hoisting bars 32 pushed intoan out-of-the-way position under the combustion chamber section 12. Therod members are then passed through the brackets 50 and the two sectionspulled completely together by tightening the threaded members 51. Afterjoining the two sections, the chimney, guillotine door, and ash removaldoors can be installed to complete the on-site assembly of theincinerator.
